OAKLAND – A 25-year-old woman who gave birth to a dead premature son on a sidewalk last week and walked away was released from custody Tuesday after an autopsy determined the child was stillborn, police said.

Police who interviewed Sanece D. Jarvis said they were upset with her nonchalant attitude — including laughing occasionally — but had no choice except to release her since she had no outstanding warrants.

“She was pretty much nonchalant,” homicide Sgt. James Morris said. “She wasn’t sorry she got caught and she didn’t seem concerned about what happened. She thought it was funny.”

According to police, Jarvis, a transient, gave birth on the sidewalk in the 1400 block of 65th Avenue about 4:35 p.m. Friday. A passerby asked her if she was all right but she walked away, her clothes covered in blood. She was stopped by police several blocks away.

The infant, who firefighter paramedics estimated to be about five months along, was pronounced dead at the scene.

When interviewed at Highland Hospital that night by police, Jarvis remembered having the child but claimed amnesia when it came to her name. She has a minor criminal record for petty theft and was officially identified by fingerprints. She has used other names in the past.

In another interview Sunday night at police headquarters with Morris and Sgt. Todd Crutchfield, Jarvis said she was a prostitute, crack cocaine user and only knew for a month she was pregnant. She thought the father was one of her customers, police said.
